Abstract
Non-plugging contact surfaces (7) are arranged at the surface of a new type of portable data carriers (3). The contact surfaces (7) establish a galvanic contact with adjacent data carriers (3) and at the same time with a bus system when several data carriers (3) of the same type are stacked. A substantially square-shaped adapter (1) has a PCMCIA standardised connection (8) that can be plugged into the equipment terminal strip and at least one cavity (2) for receiving at least one stackable data carrier (3). Mating contact surfaces (6) arranged in the receiving cavity (2) contact the contact surfaces (7) of a data carrier (3) placed in the cavity.

Schnittstellen-Adapter zur Verbindung einer PCMCIA-Anschlu߬ leiste mit Kontaktflächen eines stapelbaren, kartenförmigen DatenträgersInterface adapter for connecting a PCMCIA connector strip with contact surfaces of a stackable, card-shaped data carrier
Die Erfindung betrifft einen Schnittstellen-Adapter zur Ver¬ bindung einer auf PCMCIA (Personal Computer Memory Card In¬ ternational Association)-Standard genormten Anschlußleiste, die steckbare Kontakte enthält, mit mindestens einem stapel¬ baren, kartenförmigen Datenträger, an dessen Oberflächen nicht-steckbare Kontaktflächen angeordnet sind.The invention relates to an interface adapter for connecting a connector strip standardized to the PCMCIA (Personal Computer Memory Card International Association) standard, which contains pluggable contacts, with at least one stackable, card-shaped data carrier, on the surfaces of which are non-pluggable Contact areas are arranged.
Die bisherigen, allgemein als Chipkarte bezeichneten Daten- träger mit standardisierten Abmessungen enthalten in der Re¬ gel Halbleiterspeicherelemente mit relativ geringer Speicher¬ kapazität und eine im Vordergrund stehende Logikschaltung. Mit der zunehmenden Verfügbarkeit kostengünstig herstellbarer Halbleiterspeicher, die eine Speicherkapazität im Megabit-Be- reich bzw. weit darüber aufweisen, entsteht der Wunsch, schnell und bequem auf eine Vielzahl gleichartiger Datenträ¬ ger größtmöglicher Speicherkapazität zugreifen zu können. Diese Datenträger sollen beispielsweise für digitalisierte Musiksignale, Software für Datenverarbietungsanlagen usw. be- reitgestellt werden. Die Halbleiterspeicher können beschreib¬ bare und löschbare Speicher oder nur Lese-Speicher (ROM) sein. Vorzugsweise sind die Daten in Bezug auf ihre Redundanz komprimiert gespeichert.The previous data carriers, generally referred to as chip cards, with standardized dimensions generally contain semiconductor memory elements with a relatively small memory capacity and a logic circuit which is in the foreground. With the increasing availability of inexpensive semiconductor memories that have a storage capacity in the megabit range or far above, there is a desire to be able to access a large number of similar data carriers of the largest possible storage capacity quickly and easily. These data carriers are to be made available, for example, for digitized music signals, software for data processing systems, etc. The semiconductor memories can be writable and erasable memories or just read memories (ROM). The data are preferably stored in compressed form with regard to their redundancy.
Bisher sind insbesondere auch sogenannte Memory-Cards bekannt geworden, die vornehmlich als Zusatzspeicher für Informatio¬ nen in Personalcomputern dienen und als einfache, an den PC anschließbare Speicherkarten mit parallelem Zugriff anzusehen sind. Die Memory-Cards verfügen über nicht- flüchtige oder mit Batteriestrom versorgte Halbleiterspeicher. Damit ein schneller Zugriff auf den Speicherinhalt möglich ist, müssen viele parallele Datenleitungen zur Verfügung gestellt werden.
Für den Einsatz der Memory-Cards wurde ein spezieller Steck¬ verbinder entwickelt und gemäß der PCMCIA standardisiert, wo¬ bei auch Daten der JEIDA (Japan Electronic Industrie Develop¬ ment Association) verwendet wurden. Dieser Steckverbinder ist allgemein unter der Abkürzung "PCMCIA-Stecker" bekannt und enthält derzeit geräteseitig 68 Stiftanschlüsse bzw., karten- seitig, 68 Buchsen. Die mechanische Implementierung erfolgt üblicherweise so, daß im PC-Gehäuse ein bis drei Führungs¬ schienen für unterschiedliche Kartendicken und außerdem ein Auswurfmechanismus für die Memory-Karten vorgesehen werden. Ein PCMCIA-kompatibles Interface-System für die üblichen Me¬ mory-Cards ist beispielsweise in der US-Patentschrift 5,334,046 beschrieben.So far, so-called memory cards have become known, which serve primarily as additional storage for information in personal computers and are to be regarded as simple memory cards with parallel access that can be connected to the PC. The memory cards have non-volatile or battery-powered semiconductor memories. In order for the memory contents to be accessed quickly, many parallel data lines must be made available. A special plug connector was developed for the use of the memory cards and standardized according to the PCMCIA, whereby data from the JEIDA (Japan Electronic Industry Development Association) were also used. This connector is generally known under the abbreviation "PCMCIA connector" and currently contains 68 pin connections on the device side or 68 sockets on the card side. The mechanical implementation usually takes place in such a way that one to three guide rails for different card thicknesses and also an ejection mechanism for the memory cards are provided in the PC housing. A PCMCIA-compatible interface system for the usual memory cards is described, for example, in US Pat. No. 5,334,046.
Die herkömmlichen Datenträgeranordnungen, insbesondere die Memory-Cards, sind zur Speicherung größerer Datenmengen nur bedingt geeignet. Wenn ein Verarbeitungsgerät auf mehrere PCMCIA-Karten zugreifen soll, muß entweder ein Kartenwechsel durchgeführt werden oder aber es muß, sofern mehrere Karten gleichzeitig eingesteckt bleiben, für jede Karte eine ent¬ sprechende Anschlußbuchse im Verarbeitungsgerät vorhanden sein. Diese Anschlußeinrichtungen benötigen relativ viel Vo¬ lumen.The conventional data carrier arrangements, in particular the memory cards, are only of limited suitability for storing larger amounts of data. If a processing device is to access several PCMCIA cards, either a card change must be carried out or, if several cards remain inserted at the same time, there must be a corresponding connection socket in the processing device for each card. These connection devices require a relatively large volume.
Um gleichzeitig eine Vielzahl gleichartiger Datenträger ohne aufwendige zusätzliche Hilfsmittel an ein Verarbeitungsgerät anschließen zu können, wird in der älteren deutschen Anmel¬ dung Nr. P 44 35 122.4 ein stapelbarer Datenträger ohne eige¬ ne Steckkontakte vorgeschlagen, bei dem die Kontaktflächen vorzugsweise bündig um eine der Kantenflächen des Trägerele¬ ments umlaufend angeordnet sein sollen. Dadurch ist beim Auf¬ einanderlegen gleichartiger Datenträger ein galvanischer Kon¬ takt zu den jeweils benachbarten Datenträgern und gleichzei¬ tig zu einem Bussystem möglich.In order to be able to simultaneously connect a large number of data carriers of the same type to a processing device without complex additional aids, in the older German application No. P 44 35 122.4 a stackable data carrier without its own plug contacts is proposed, in which the contact surfaces are preferably flush with one of the Edge surfaces of the carrier element should be arranged all around. As a result, when data carriers of the same type are placed one on top of the other, galvanic contact with the adjacent data carriers and simultaneously with a bus system is possible.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, Vor¬ aussetzungen zu schaffen, um die neuartigen, stapelbaren Da-
tenträger, die selbst keine steckbaren Kontakte enthalten, über eine an handelsüblichen Datenverarbeitungsgeräten be¬ reits vorhandene Schnittstelle, hier die PCMCIA-Anschlußlei¬ ste, an diese Verarbeitungsgeräte anschließen zu können.The object of the present invention is to create the conditions for the novel, stackable data Carriers, which themselves do not contain any pluggable contacts, can be connected to these processing devices via an interface which is already present on commercially available data processing devices, here the PCMCIA connecting bar.

Die Erfindung wird nachfolgend anhand von Aus¬ führungsbeispielen eines Schnittstellen-Adapters im Zusammen¬ hang mit Figuren näher erläutert. Es zeigen:Further embodiments of the invention are the subject of the subclaims. The invention is explained in more detail below on the basis of exemplary embodiments of an interface adapter in connection with figures. Show it:

Figur 2 in gleicher Darstellung eine bekannte PCMCIA-An¬ schlußleiste mit Stiften.FIG. 1 shows a perspective top view of an adapter according to the invention, Figure 2 in the same representation a known PCMCIA connection strip with pins.
In Figur 1 ist ein quaderförmiger Adapter 1 mit einem zur Oberseite hin offenen Aufnahmeraum 2 dargestellt. Der Adapter 1 entspricht flächenmäßig etwa der üblichen Scheckkarten¬ größe, während seine Dicke, dem PCMCIA-Standard entsprechend, 3, 6 oder 12 mm betragen kann. Insbesondere bei einer 12 mm- Adapter-Version können deshalb ohne weiteres auf beiden1 shows a cuboid adapter 1 with a receiving space 2 that is open toward the top. In terms of area, the adapter 1 corresponds approximately to the usual credit card size, while its thickness, in accordance with the PCMCIA standard, can be 3, 6 or 12 mm. With a 12 mm adapter version in particular, you can therefore easily use both
Hauptflächen des Adapters jeweils mindestens ein zu dieser Hauptfläche hin offener Aufnahmeraum 2 vorgesehen werden. Bei der in Figur 1 dargestellten speziellen Ausführungsform von Adapter 1 und Datenträger 3 können nebeneinander drei Daten- träger 3 in den Aufnahmeraum 2 eingelegt werden. Die Anzahl der in den Adapter 1 einlegbaren Datenträger 3 ist im wesent¬ lichen von deren Größe abhängig. Da der Speicherchip selbst nur eine Fläche von ca. 1 cm^ in Anspruch nimmt, sind Daten¬ trägergrößen bis hinab zu etwa 1/8 des Scheckkartenformats realisierbar.Main surfaces of the adapter are each provided at least one receiving space 2 open to this main surface. In the special embodiment of adapter 1 and data carrier 3 shown in FIG. 1, three data carriers 3 can be inserted next to one another in the receiving space 2. The number of data carriers 3 that can be inserted into the adapter 1 essentially depends on their size. Since the memory chip itself only takes up an area of approximately 1 cm, data carrier sizes down to approximately 1/8 of the credit card format can be realized.
Es ist vorteilhaft, am Adapter 1 und an den Datenträgern 3 Mittel vorzusehen, beispielsweise die in Figur 1 dargestell¬ ten Nasen 4, bzw. Nuten 5, die ein lagerichtiges Einlegen der Datenträger 3 in den Adapter 1 gewährleisten. In den Daten¬ trägern 3 können beispielsweise auch Mulden eingearbeitet sein, die einen manuellen Eingriff von außen her und damit das Herausnehmen des Datenträgers 3 aus dem Adapter 1 er¬ leichtern.It is advantageous to provide means on the adapter 1 and on the data carriers 3, for example the lugs 4 or grooves 5 shown in FIG. 1, which ensure that the data carriers 3 are inserted in the correct position in the adapter 1. Troughs can also be incorporated in the data carriers 3, for example, which facilitate manual intervention from the outside and thus the removal of the data carrier 3 from the adapter 1.
In Figur 1 sind außerdem auf der Bodenfläche des Aufnahme¬ raums 2 reihenartig nebeneinander angeordnete Gegenkontakt- flächen 6 für die an Oberflächen des Datenträgers 3 jeweils angeordneten Kontaktflächen 7 angedeutet. Die stapelbaren Da- tenträger 3 werden typischerweise lediglich 8 Anschlüsse auf¬ weisen. Wenn mehrere Aufnahmeräume 2 bzw. mehrere Plätze für Datenträger 3 in einem Aufnahmeraum 2 vorgesehen sind, so
werden die zugehörigen Gegenkontaktflächen 6 im Adapter un¬ tereinander verbunden, wie in Figur 1 angedeutet. Ein oder mehrere Datenträger 3 werden in einen Adapter 1 eingelegt und kontaktieren die dort befindlichen Gegenkontaktflächen 6, die in einer 68-poligen Buchsenleiste 8 (PCMCIA-Konfigura¬ tion),dem Anschlußgegenstück, enden, wobei vorzugsweise le¬ diglich 8 Durchgänge benützt werden. Die datenträgerseitig beispielsweise 8 Kontakte werden also anschlußleistenseitig mit 8 oder mehr der dortigen 68 Kontakte verbunden. Der so mit Datenträgern 3 bestückte Adapter 1 kann nun in den ent¬ sprechenden PCMCIA-Slot eines Verarbeitungsgerätes, der bei¬ spielsweise wie in Figur 2 schematisch gezeigt aufgebaut sein kann, geschoben werden, wobei es letztlich zum Steckkontakt zwischen der geräteseitigen Anschlußleiste und dem Anschluß- gegenstück δdes Adapters 1 kommt. Ein oder mehrere Datenträ¬ ger 3 können jedoch auch nachträglich in den im Slot befind¬ lichen Adapter 1 geschoben werden, sofern kantenseitig eine Öffnung im Adapter 1 vorgesehen wird. Es ist ohne weiteres auch möglich, an einem Kartenplatz des Aufnahmeraums 2 minde- stens zwei übereinander gestapelte und mittels ihrer Kon¬ taktflächen 7 seriell verbundene Datenträger 3 anzuordnen.In FIG. 1 there are also indicated on the bottom surface of the receiving space 2 rows of counter-contact surfaces 6 arranged side by side for the contact surfaces 7 respectively arranged on surfaces of the data carrier 3. The stackable data carriers 3 will typically only have 8 connections. If a plurality of recording spaces 2 or a plurality of spaces for data carriers 3 are provided in a recording space 2, then the associated mating contact surfaces 6 are connected to one another in the adapter, as indicated in FIG. 1. One or more data carriers 3 are inserted into an adapter 1 and contact the mating contact surfaces 6 located there, which end in a 68-pin socket 8 (PCMCIA configuration), the connection counterpart, preferably only 8 passages being used. The data carrier side, for example, 8 contacts are thus connected to 8 or more of the 68 contacts there on the terminal strip side. The adapter 1 thus equipped with data carriers 3 can now be pushed into the corresponding PCMCIA slot of a processing device, which can be constructed, for example, as shown schematically in FIG. 2, it ultimately being used for the plug contact between the device-side connection strip and the connection - counterpart δ of the adapter 1 comes. However, one or more data carriers 3 can also be subsequently pushed into the adapter 1 located in the slot, provided that an opening is provided in the adapter 1 on the edge side. It is also readily possible to arrange at least two data carriers 3 stacked one above the other and serially connected by means of their contact surfaces 7 at a card slot in the receiving space 2.
Das erfindungsgemäße Adapter-Konzept, das zunächst nur eine elektromechanische Anpassung an die PCMCIA-Konfiguration ge- währleistet, kann durch im Adapter integrierte Mittel ohne weiteres zur elektronischen Anpassung eines anschlußleisten¬ seitig parallel organisierten und datenträgerseitig seriell organisierten Datenzugriffs erweitert werden. Die elektri¬ schen Kontakte der Anschlußleiste entsprechen beispielsweise PC-seitig den Adreß- und Datenleitungen eines Mikrocomputers. Wenn beispielsweise ein spezieller integrierter Schaltkreis im Anschlußgegenstückbereich 9 des Adapters 1 angeordnet und den Buchsenanschlüssen des Anschlußgegenstücks 8 vorgeschal¬ tet ist, können die in den Adapter 1 eingelegten Datenträger 3 im Ergebnis als Speichererweiterungskarte am Systembus des Mikrocomputers betrachtet werden.
In einer weiteren, in den Figuren nicht dargestellten Ausge¬ staltung der Erfindung ist vorgesehen, daß an einer dem An¬ schlußgegenstück 8 gegenüberliegenden Kante des Adapters ein Steckverbinder angeordnet ist, an den ein externer Kartensta¬ pel mittels eines Steckers anschließbar ist. Dieser Stecker kann beispielsweise mittels eines Kabels mit einer Kartensta- pelanordnung verbunden sein.
The adapter concept according to the invention, which initially only ensures an electromechanical adaptation to the PCMCIA configuration, can easily be expanded by means integrated in the adapter for the electronic adaptation of a data access which is organized in parallel on the terminal strip side and is serially organized on the data carrier side. The electrical contacts of the terminal strip correspond, for example, on the PC side to the address and data lines of a microcomputer. If, for example, a special integrated circuit is arranged in the connection counterpart area 9 of the adapter 1 and the socket connections of the connection counterpart 8 are connected upstream, the data carriers 3 inserted into the adapter 1 can be considered as a memory expansion card on the system bus of the microcomputer. In a further embodiment of the invention, not shown in the figures, it is provided that a connector is arranged on an edge of the adapter opposite the connection counterpart 8, to which an external card stack can be connected by means of a connector. This connector can be connected to a card stack arrangement, for example, by means of a cable.
